一．准备工作

1.Tkinter

Tkinter 是 python 内置的 TK GUI 工具集。TK 是 Tcl 语言的原生 GUI 库。作为 python 的图形设计工具，它所使用的 Tcl 语言环境已经完全嵌入到了 python 解释器中。

我们使用Tkinter开发GUI界面。

2.PIL

• PIL(Python Image Library)库是Python语言的第三方库，需要通过pip工具安装。安装PIL库的方法如下，需要注意，安装库的名字是pillow。
• PIL库支持图像储存、显示和处理，他能够处理几乎所有图片格式，可以完成对图像的缩放、剪裁、叠加以及向图像添加线条、图像和文字等操作。

使用PIL中的Image,ImageTk处理、引入一张图片，可以使用下面代码安装一下。

pip install pillow

二．预览

1.启动

双击打开后，进入软件主界面，所有功能一目了然。程序会自动识别软件目录下的names.txt，将里面的名字导入。

2.开始点名-顺序点名

选择顺序点名后，点击开始，屏幕上就开始滚动出现人名，人名出现的概率是相同的，点击停止，人名就停止滚动，点名结束。

3.开始点名-随机点名

点击随机点名，程序就会进行随机点名，人名出现的概率是随机的。

4.手动加载人名单

可以自己手动选择人名单，前提是人名单格式为txt，且每个名字占一行。

5.开始点名-顺序点名-Pyqt5版本

用Pyqt5也写了一个版本，实现逻辑与TK版本相同，界面可能更好看了一些，但是文件大了许多，大家可以在后面总结部分自取。

三．思路

1.整体实现思路

2.点名实现思路

四．源代码

point_names-GUI.py（主程序GUI）
import random
import re
import time
import threading
from tkinter import *
from tkinter import ttk
from base64 import b64decode
from PIL import Image,ImageTk
from tkinter import messagebox
from tkinter.filedialog import askopenfilename


""""
2021-11-10点名/抽奖程序
主要亮点：
1.两种模式：
①顺序点名
②随机点名
2.自动识别人名单
3.支持手动导入人名单
4.人名单导入校验
5.人名显示位置自动矫正
6.最多显示五个大字

五．总结

本次使用Tkinter开发了一款上课点名程序，此程序可以用于点名、抽奖…代码不到200行，程序简单又实用，

主要有以下六个亮点：

1.两种模式：

• 顺序点名
• 随机点名

2.自动识别人名单

3.支持手动导入人名单

4.人名单导入校验

5.人名显示位置自动矫正

6.最多显示五个大字
